Have you put your references? Because for me, I understand that there are some parts that you will refer to other projects or as you said when you are talking with crypto history, you got it from other sources. There's no problem with that, but not word for word. At least re-phrase and provide the references that you used. If you already edited your wp, that's fine for me as long as you are not scamming anyone. I guess plagiarism is very common among crypto projects. Very few start from scratch.
The most important thing regarding their whitepaper is that it contains useless definitions copied from the Internet and nothing else. Whitepaper can tell you what bitcoin is, what blockchain is, what proof-of-work is, etc, all the information you usually don't need to use to explain how your project works. You're right plagiarism is very common story among crypto projects, but there's no justification for it. If developers want to succeed, they must make a project from scratch, without copying other people's ideas and documents.
